Torque and service life at rated speed
The GBX1200250704F delivers 230 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent rating of 368 N.m at the same speed and temperature. Service life is specified at 30,000 hours under continuous rated load.
Mechanical interface and load capacity
This 120 mm diameter planetary gearbox uses straight teeth and a C 45 steel output shaft in a black anodized aluminium housing. Maximum radial force at mid-span on the output shaft is 1500 N for the 30,000-hour life target, or 2000 N if the application accepts a shorter 10,000-hour service interval. Maximum axial thrust is 2100 N at the same 30,000-hour rating, rising to 2800 N for the 10,000-hour duty.
Efficiency, backlash, and noise floor
Rated efficiency is 94 %, with maximum torsional backlash at 12 arc-min and torsional rigidity of 13 N.m/arcmin. Noise level at 1 m under no-load conditions is 65 dB. The unit is lubricated for life and sealed to IP54 at the shaft output.
Sourcing an obsolete planetary gearbox
Schneider Electric lists the GBX1200250704F as obsolete.
